Four springs are each stretched by a force of 10 N. None of the springs is inelastically deformed. Which spring stores the most elastic potential energy?
the spring with a spring constant of 500 N/m500\ \text{N/m}500 N/m
the spring with a spring constant of 250 N/m250\ \text{N/m}250 N/m
the spring with a spring constant of 100 N/m100\ \text{N/m}100 N/m
the spring with a spring constant of 50 N/m50\ \text{N/m}50 N/m
